DMEGC AC Module Installation Manual
- 3 -
WARNINGS:
Before installing or using the Enphase Microinverter, read all instructions and cautionary markings in the
technical description, on the Enphase equipment and on the photovoltaic (PV) equipment.
Do not connect Enphase Microinverters to the grid or energize the AC circuit(s) until you have completed all of
the installation procedures and have received approval from the electrical utility company.
When the PV array is exposed to light, DC voltage is supplied to the power conversion equipment (PCE).
Risk of equipment damage. Enphase male and female connectors must only be mated with the matching
male/female connector.
NOTES:
To ensure optimal reliability and to meet warranty requirements, install all equipment according to the
instructions in this manual.
The AC and DC connectors on the cabling are rated as a disconnect only when used with an Enphase
Microinverter.
Protection against lightning and resulting voltage surge must be in accordance with local standards.
Perform all electrical installations in accordance with all applicable local electrical codes.
Microinverter Safety
WARNING:
Risk of skin burn.
The body of the Enphase Microinverter is the heat sink. Under normal operating conditions, the temperature
could be 20 C above ambient, but under extreme conditions the microinverter can reach a temperature of 90 C. To
reduce risk of burns, use caution when working with microinverters.
DANGER:
Risk of electric shock. Risk of fire.
Only qualified personnel may connect the Enphase Microinverter to the utility grid.
Do not attempt to repair the Enphase Microinverter; it contains no user-serviceable parts. If it fails, contact
Enphase customer service to obtain a return merchandise authorization (RMA) number and start the replacement
process. Tampering with or opening the Enphase Microinverter will void the warranty.
